The RW Universe (Real World Universe) is a parallel universe in which Half-Life and City 17 Street are seen as complete fiction.
The universe was discovered when Toby Purnell used an upgraded displacement cannon to bounce across the multiverse, which led him to the real world. Nathan Johnson was sent to this universe by the Elder Supreme in order to prevent Toby from manipulating their own world. Toby was imprisoned, and Nathan remained in the real world.
An unknown force merged both the real world and the C17 Universe, which gave birth to another brand new timeline.
